Question

I plan to use XMLHttpRequest “post” text/string to server from client side. I need the text/string to be saved. I am new to XMLHttpRequest. I see a lot javascript coding but few server side coding. How can I process XMLHttpRequest at server side with asp.net/c#? Many thanks.

xhr.open("POST", "processing.aspx", true); 
xhr.setRequestHeader("Content-Type", " "); 
var data = " ";                 
xhr.send(data);

this is the javascript code to send data. I need some code example “processing.aspx” to save data at server side.

You can post to a web method like below using javascript.

 [System.Web.Services.WebMethod]
 public static object GetData(string strFromHttpRequest)
    {

        return yourData;
    }

here is a good tutorial to sart.
